The present invention relates to a golden ornament suitable for accessories such as bracelets.

What has been disguised as has been prized. However, gold is so expensive that for economic reasons one should use as little gold as possible. Further, in a practical accessory such as a watch side, the coating of gold or a gold-containing substance having a thin surface is easily worn by sweat or friction.

低いＬ値を有するにすぎない。Therefore, as disclosed in Japanese Patent Publication No. 59-26664, there is a high hardness between a substrate and a gold or gold-containing substance under a coating layer, and good corrosion resistance, wear resistance and oxidation resistance. A decorative article has been developed, which is provided with a coating layer of a golden hard metal made of titanium nitride. However, the coating layer made of titanium nitride is clearly different from the color of gold itself, does not give a true gold color, and even if another metal is mixed with titanium nitride, the luster peculiar to gold is insufficient. Therefore, even though it is a color close to the gold coating layer at the wear point, the reflectance is low for visible light due to lack of gloss, and it gives a generally dark greenish tint, which is different from the beautiful color unique to gold. Limited application in goods. For example, Japanese Patent Laid-Open No. 61-
As pointed out in Japanese Patent No. 117270, in CIELAB units, the L value that characterizes the gloss requires a glossiness of 80 or more, particularly 85 or more in order to actually use it as a decorative article. The coating layer consisting of only has a significantly lower L value.

が減るという結果をもたらす。Therefore, as a gold-colored hard material replacing the titanium nitride coating layer, Japanese Patent Application Laid-Open No. 61-117270 discloses a material having an intermediate coating layer made of titanium carbonitride. However, as is clear from the description on “High-performance coating by vacuum technology” published by Nikkan Kogyo Shimbun, edited by Saburo Tabata and Kiyoshi Huangyan, page 245, when hydrocarbon gas is added to titanium nitride to form titanium carbonitride, As shown in FIG. 1, the flow rate of the hydrocarbon gas has a great influence on the hue and saturation of the titanium nitride film, and the hue tends toward red, and at the same time, the saturation decreases.

赤白色の方向に変化することが知られている。On the other hand, when titanium oxynitride is obtained by adding oxygen gas to titanium nitride, a small amount of addition gives a hue closest to the color peculiar to gold as shown by the chain line in FIG. Although it increases, it is known that the hue changes to red and white when a certain amount or more of oxygen gas is added.

品を提供することが求められている。(Problems to be solved by the invention) In ornaments, since the luster and color are extremely rigorously discriminated, an intermediate coating layer similar to the color unique to gold is used as the base of the outermost layer of gold or a gold-containing substance. There is a demand for providing a golden-colored decorative article that is configured and has almost no color change even if the outermost surface gold coating layer is worn.

的とする。The present invention has clarified the ratio of N and O of titanium oxynitride suitable as an intermediate coating layer for the outermost layer of gold or a gold-containing substance of a decorative article, and has the same color as that of gold or a gold-containing substance. The purpose of the present invention is to provide an inexpensive ornamental product which can be made extremely thin in thickness of gold because of its excellent corrosion resistance.

設による痕跡を一層識別することが困難である。That is, the intermediate coating layer of the present invention is formed as follows. That is, the dissolved titanium is coated in a nitrogen gas to which oxygen gas is added so that O is 0.5 to 6 atom%, preferably 0.8 to 4.5 atom% with respect to the total amount of N and O of titanium oxynitride to be formed. Thus, a coating layer of Ti (N x O y ) z solid solution having a color unique to gold or a gold alloy is provided, and an intermediate coating layer having a color closest to that of gold or a gold-containing substance is formed. Therefore, the coating layer formed by a specific ratio of Ti (N x O y) z, it is difficult to further identify traces by milling set in comparison with titanium or carbo titanium nitride nitride.

The area surrounded by the solid line is close to the color of gold or a gold-containing substance, and is practical.

However, it can also be applied to cemented carbide, cermet, ceramics and plastics. These substrates are coated with Ti (N x O y ) z by a known method using a mixed gas of N 2 and O 2 by an ion plating method or a cathode sputtering method.

After raising the temperature to 0 ° C and Ar bombarding at 0.1 Torr for 10 minutes and exhausting, Ti is melted by a hollow cathode gun and 95% N 2 -7% O 2 as a reaction gas (hereinafter, the gas composition is %), And a mixed gas having a composition of 1.4 × 10 −3 T
Introduced to orr to cover Ti (N 0.95 O 0.05 ) 0.98 . The bias during coating was 30V. The watch case thus obtained is referred to as Sample 1.

A 26.5% Ag-15% Cu alloy (hereinafter, alloy composition represents% by weight) is sputtered in vacuum to coat the surface of each of sample 1 and sample 2 with a gold alloy having a thickness of 0.2 μm. A watch case having the following color tone was obtained. The sample 1 to which the gold alloy is applied is referred to as sample 1-a, and the sample 2 to which the gold alloy is applied is referred to as sample 2-a.

The color tone of the 0.98 coating layer was similar to that of the outer gold alloy layer (1N-14), so it was not very noticeable, and the appearance as a watch was still pleasing to watch. On the other hand, Sample 2-a had a large difference between the color tone of the TiN 0.97 coating layer and the color tone of the outer gold alloy layer, and therefore, it was judged that it had a loss of appearance as a decorative article and was considered to have a long life. It was

Ti (N) similar to the color tone of the gold alloy layer (1N-14)
It was found that the practical life was extended several times when 0.95 O 0.05 ) 0.98 was used.

Ar bombarded at orr for 15 minutes and then evacuated. Then, a hollow cathode gun was used to dissolve the titanium metal, and a mixed gas having a composition of 98% N 2 -2% O 2 was added as a reaction gas to 9.7.
Ti (N 0.98 O 0.02 ) was coated by introducing up to × 10 -4 Torr. The bias voltage during coating was 5V. The watch case thus obtained is referred to as Sample 3.

A watch case having a color tone of -18 was obtained. The sample 3 to which the gold alloy was applied was referred to as sample 3-a, and the sample 4 to which the gold alloy was applied was referred to as sample 4-a.
試料３−ａ及び試料４−ａについて、実施例１と同様の
摩擦テストを行い、金合金の摩滅により、下地が部分的
に露出した。しかし、試料３−ａは、下地の色調が外層
の金合金の色調2N−18に近いために目立たないのに比
べ、TiNを下地に被覆した試料４−ａは、下地の色調が2
N−18と大きく異なるため、外観的には寿命と判断され
た。The same friction test as in Example 1 was performed on Samples 3-a and 4-a, and the base was partially exposed by abrasion of the gold alloy. However, Sample 3-a is not noticeable because the color tone of the base is close to the color tone 2N-18 of the gold alloy of the outer layer, whereas Sample 4-a coated with TiN as the base color has a color tone of 2
Since it is significantly different from N-18, it was judged to be the end of life in appearance.

ができる。[Effects of the Invention] The intermediate coating layer of titanium oxynitride in the golden ornament of the present invention has a color of gold or a gold-containing substance (for example, Swiss standard 1N-
14,2N-18) and specular gloss. Therefore, even if the outermost layer of gold or a gold-containing substance is worn, there is almost no change in color, which is excellent in that the value as a decorative article is not reduced. Therefore, the outermost layer of gold or a gold-containing substance can be made thinner, and an inexpensive outer package can be provided.
